I look after a Z way installation with 10 devices. All working fine until now when one device has disappeared.... just vanished. It's not dead or anything like that, just gone from the UI. I use a custom front end and my API calls for that are just being ignored, although interestingly a IsNodeFailed check for the device responds saying the device is alive... but no switch commands seem to be working or appearing in the job queue.

Device in question is a Fibaro FGS222. Using Z Way 2.3.0. This node is on the edge of the z wave range but usually works fine, but sometimes needs one or two re transmissions to succeed - but it gets there eventually.

Interestingly this isn't the first time it has happened - with this device either. It happened to this 'switch' (same location, but different module) about 3 months ago and I just swapped the module over assuming the module had failed - but now the same thing has happened again.

When I send a switch command in my front end that will login to the Z Way API and send a IsNodeFailed check, and then directly after send the switch command, but all I see in the logs is:

Any ideas, other than reincluding the device? I don't have access to it for another 2 weeks and its in a hard to get location. Don't really want to look a tit to the client and tell them its done the same thing it did before
